Don't fear objections. Someone who's said nothing isn't interested. Someone who says "but what about..." is already picturing it. There's a simple way to answer every one of them.
- Stop talking, and let them finish
- Agree with what's true in it: "That's fair"
- Ask one question to find out what they really mean
- Answer only that, honestly and briefly
- Ask if that helps. Then move to one small next step
